Problems solved by technology

The traditional method is to use HDMI cables for multimedia signal transmission, but when using ordinary HDMI cables for long-distance transmission, the output signal is often poor, easy to be interfered, and the displayed image will appear blurred, trailing, color separation, etc. ; At the same time, the transmission distance of HDMI cable transmission is short, which cannot meet the needs of many occasions that require long-distance transmission and release of multimedia information.

Abstract

The invention provides an HDMI multi-service optical transceiver comprising a source-side device and a target-side device. The source-side device comprises a first signal unit, a second signal unit, a third signal unit and a first clock unit. The target-side device comprises a switch chip, a first decoding unit, a second decoding unit, a third decoding unit and a second clock unit. The signal units and the first clock unit of the source-side device are electrically connected with a signal source when used, and are electrically connected with the decoding units and the second clock unit by signals through the switch chip of the target-side device. The output ends of the decoding units and the output end of the second clock unit are electrically connected with target equipment when used. Each of the signal units comprises an encoder and a serializer. Each of the decoding units comprises a decoder and a serializer. The HDMI multi-service optical transceiver has the characteristics of low transmission attenuation, wide bandwidth, strong anti-interference capability, high safety performance and long transmission distance. When used, the HDMI multi-service optical transceiver is convenient in wiring, saves construction cost and satisfies a plurality of using requirements.

Description

technical field [0001] The invention relates to multimedia information transmission equipment, in particular to an HDMI multi-service optical transceiver used for HDMI digital audio and video signal transmission. Background technique [0002] In today's society, multimedia information has been widely used. In multimedia application systems, it is often necessary to transmit HDMI digital audio and video signals over long distances. The traditional method is to use HDMI cables for multimedia signal transmission, but when using ordinary HDMI cables for long-distance transmission, the output signal is often poor, easy to be interfered, and the displayed image will appear blurred, trailing, color separation, etc. ; At the same time, the transmission distance of HDMI cable transmission is short, which cannot meet the needs of many occasions that require long-distance transmission and release of multimedia information. Contents of the invention [0003] The purpose of the prese...
